Earlier this year a new national marine sanctuary was established about 40 miles south of Washington, DC to protect the remains of more than 100 abandoned steamships and vessels (referred to as the “Ghost Fleet”) built as part of America’s engagement in World War I. Although the ships never saw action during the war, their construction at more than 40 shipyards in 17 states reflected the massive national wartime effort that drove the expansion and economic development of waterfront communities and maritime service industries. The oldest ships sank there in the 1700s; the most recent ones are from the 20th century. Their skeletal remains rise up in the air, looking like spirits rising out of the Potomac River. It is said to be the first sanctuary to protect not only sea creatures, but also partially covered shipwrecks.
